Abstract: ABSTRACT            A TONE RECEIVER FOR DIGITAL DATA COMMUNICATION SYSTEMS            A device for detecting the presence of an alarm tone of a given frequency within a received signal carrying digital data in addition to said tone.  The receiver comprises an analog-to-digital converter the output of which is applied to a first recursive bandpass filter centered at the frequency of the alarm tone and the feedback loop of which includes a limiter.  In addition, an input feedforward loop is provided for adding the output signal from the converter, as multiplied by a coefficient ?, to the output signal from the limiter.  The output signal from the adder is hard limited, then passed through a second bandpass filter.  The energy of the signal obtained at the output of said second filter is then measured to provide indication of a tone being received when said energy exceeds a predetermined threshold,

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention relates to a device for cleaning teeth and massaging gums.  The toothbrush used up to now for such purposes has certain disadvantages and, furthermore, caused by its nature and size it is not always on hand when dental hygiene necessitates it.  The device as defined in the invention is characterized by a small sheet provided with a multitude of bristles or bristlelike projections whish is suitably dimensioned and is provided on its front side with a dentifrice and on its back side with an adhesive which makes possible the attaching on a finger tip.  It creates a kind of "disposable toothbrush" which is hygienic and always ready to use and can always be on hand due to the small dimensions.

Abstract: ABSTRACT     LINK BELTS     The invention proposes the use, in the manufacture of link belts, of helical coils wound from elongate synthetic plastics material of non-circular, and preferably generally rectangular, transverse cross-section, the major dimension of the said cross-section extending widthwise of the link belt.          By using, for example, flat monofilament yarns of a given cross-section in the production of an oval coil of a related major dimension it is possible to increase the cross-section of the wire receiving tunnel formed by two interdigitated coils without prejudice to the capability of interdigitated coils to remain in mutual engagement, and thus facilitate the introduction of hinge wires by mechanical means.

Abstract: Abstract SUMMARY            A Method and a Device for Controlling the Distribution of Brake Force according to DBP... (Patent Application P 33 01 948.7) With a view to controlling the distribution of brake force onto the front and rear axles of an automotive vehicle in response to the momentarily prevailing static and dynamic axle load distribution, the wheel rotational behaviour (? ) on the front axle (VA) and on the rear axle (HA) and the translational deceleration (-b) of the vehicle or variables proportional to said measured values are determined by way of sensors. After the said signals having been electronically processed and combined, the share of the brake pressure (PHA) fed to the rear axle in response to the front wheel brake pressure (PVA) is so controlled that the brake slip at the rear axle (HA) corresponds to the brake slip at the front axle (VA) or is slightly less than the front wheel brake pressure.  In the event that nontheless a locking tendency of the rear wheels occurs, e.g. as a result of rapidly changing road conditions, the brake pressure at the rear axis is reduced with the aid of another quick-acting electromagnetically operated valve (6,16) and is maintained constant at the low value until the front wheel pressure has decreased.

Abstract: ABSTRACT OF THE DISCLOSURE          A tape cassette for short-time recording is interchangeable with a long-playing standard tape cassette and has the external size and functions substantially the same as that of the standard tape cassette.  The casing of the short-time tape cassette is provided with a large aperture the area of which is larger than that of an aperture formed in the bottom of the standard tape cassette, owing to the reduction in the diameters of the reel flanges.  With this arrangement, it is possible to accommodate the mechanism including the tape path within the outside dimensions of the tape cassette, thus allowing miniaturization of the mechanism of the apparatus which handles  the tape.   At  the same  time,  a perfect interchangeability between the short-time tape cassette and the standard tape cassette is obtained, so that users can operate both types of the tape cassette on an identical player such as a VTR.
